Thanks everyone for your patience, I'm now happy to report that I, Hope will play on any Windows 7+ PC with DirectX 11+ (graphics cards later than 2011 should be fine).
Please report any problems to me, I'm happy to try to help.
Also, if you have played the game, REVIEW the game! We need as many reviews as possible, and if there's something you'd like to see in the game that would make you recommend it, let me know.
